y Application filed July 20, li.v (No model.) A* K Y To all whom, z'tmag/ concern:

Beit known that I, Li-:vi It. ROcitwoon, a cit.- izen of theUnited States, residing Vat \\`orccster, in thev county of \\`orcester and State of 5 Massachusetts, have invented certain new and 'The objects of my invention are to provide i 5 an efficient fountain for stencil-ing inks or colors froinwhich the same can be conveniently used, said fountain having a lever device for depressing the top plate for rapidly and positively forcing the ink upon the surface in such quantities as maybe required, to afford means for preventing the freezing or congealingof the ink, and also to provide means for admitting air to the interior of the fountain as the ink or coloring material is ejected. These ola- 5 jects I attain by mechanisnrthc nature and construction of which are h-erein illustrated and explained. the particular subject-matter claimed being hereinafter definitely specified,A In the drawings, 'Figure 1 is a perspective view of my improved fountain. Fig. 2 is a central vertical section of the same. -Fig. 3 is a diagram, showing plan of the re-euforce lc-4 ver and position of tube for delivering the ink to the surface of palette-plate. v

In the drawings, A denotes thercscrvoir or vessel for containing the ink or color, said vessel-which consists of a circular itat box Of sheet-brass or other suitable material-having a crowned flexible top, A', with an opening, a, for the ejcctlnent of the ink from the interior to the top surface thereof at such times and in sach quantities as may be required for use. The top A serves as a palette, from whichthc ink or color is taken upon the brush. 5 At one side, proiccting upward from thereservoir, is a hollow column or tube, B, provided with a screw cap, n C, which column serves as a filler for the reservoir, a` lever for pumping the ink to the surface of the palette'- v of thc plate A'.

plate, A', it being screwed into or otherwise fastened to a rc-enforce piece, D, that is attached to the top plate, A', and which is furnished with an armd, extending along thc f plate' A toward the orifice a. in the manner ilward,A is arranged through the cap C, for automat-ically admitting air into the interior, or, by forced depression, to allow the escape of air therefrom. Said valve is furnished ,with a spindle and knob, G', projecting above the cap,

An air- 'alve, G, to open iut UNITED STATS PATENT footV of the column is rigidl)` secured tothe top l" whereby the valve G can be opened by hand by f pressure on the knob for admitting or extracting air when desired to equalize the pressure,

H indicates a wire pin for stopping the ori- L tice ay when the apparatus is not in nse.

K is a ring Or holder forthe stcnciling-brush, ,I

attached to the column B, as indicated. Said brasil-holder is provided with a recess, 1.', for

supporting the wire stopper H when it iS`re# moved from the orifice a. (Sec Fig. 1.)

In the Operation of the apparatus the ink or y color material is forced to the surface of the palette A by pressing forward the upper-cudV of the column B, which column, acting as alever in connection with the re-en force piece I), effects the depression of the eentcrof the plate A' and tube E, causing the ink to flow up through the tube E and out upon the palet-tesurface. By a succession of backward and forward movements of the column B andthe resultant Hexa-re or vibrations of the plate- A', the contents of the reservoir A, or any portion thereof, can be pumped upon the surface of the 'palettein a. very rapid and convenient manner.

\\'l1eirtlcsixed, or forlarge-sized apparatus,

the column'- B may be braced or given addithe top 'of' the standard, while its lowercnds are secured to the reservoir at either side, as

illust lated in-Fig. v1, the wire being setto give 5o plate, and as a handle for the apparatus. The a backward strain'at its upper end.

`L indicates a hath or additional reservoir, embracing the sides and bottom of the inkreservoir A, and temporarily or permanently con 4 nected therewith' in a suitablel manner. Said bath L is for containing hot water or spirit, to,

preventtfrcezing or congealing of the ink or l colorin'the reservoirA when the apparatus is used in cold and exposed situations` Thisbath is also of service where it; is desired to use anink or color material in the fountain, which solidities at ordinary temperatures, and which requires to be liquefied by elevation of temperature before use, or. for those inks or colors which require to be used or applied hot to give the desired effective results-- i The bath L is provided with a filler or tube, M, at one side, which is tt'ed with'ra screw cap or stopper, in, for closing the orifice.

11 n indicate the springs employed 4in the present instance for confining the bath L-to reservoir A. Any other suitable means of at# tachinent may, however, be used, if preferred.

I am avvare that devices similar to the tube E andv springA F have heretofore beenuscd in combination with a depressi-ble top plate or palette, and I do not therefore herein makeA claim, broadly, to such arrangementof parts.

'hat Iclaiin as my of invention, and desire.

to secure by Letters Patent, isi-'- 1. A stencil ink or color fountain having a reservoir providcdavith a exibl'e-top plate,

in combination with a'tube or column projecting therefrom and adapted to be used as a. 1e-

ver for depressing the central portion of said top pla-te, substantially as and i'orthe purpose liereinbefore set forth.

` 2.A 'A stencil ink or color fountain having a flexible top plate provided with -a deliveryoritce communicating th rough-a tube'witli the lower part-of the reservoir, and a column or tube projecting above said top plate, in combitlatiolrwit'h'a re-enforce piece rigidly at A tached to said column, and provided with van arm extended along the top plate, to which it is attached, to act in connection with said colvumnv asa lever for depressing said top plate,

substantially as and for the purpose hereinbefore set forth. Y

3.' AIn a stencil ink orcolorfcuntain, theconibi nation, with. the reservoir having the texi- 5- bletop plate, A', and the tube or column B,

lof the re-enforce lever D, attached to and connecting said plate and column, substantially 'as and for the purpose set forth.` 4. Iuasteneilink or colorfon-ntain, thecom 5 bination, ivith the reservoir having depressi- Y ble top plate, A', internal tube, E, and tubnlar column B, adapted fordepressing said top plate, as set forth. ofthe air-valve G, adapted for automatically admitting air to thefinterior 6 and for preserving the air-pressure therein, substantially as hereinbefore setJ fort-h.

The stencil ink or color fountain constructed with the palette-surface A', reservoir scribed, and"provided n'ith'the detachable bath-reservoi r.I L, and means for securing the same to the reservoir A, in themanner shown, and for the purpose set forth.
